MVT provides two commands `mvt-ios` and `mvt-android`. [Check out the documentation to learn how to use them!](https://docs.mvt.re/)
|
||||
|
||||
### Shell completion
|
||||
|
||||
MVT can generate shell completion scripts for Bash, Zsh, and Fish:
|
||||
|
||||
```bash
|
||||
mvt-ios completion
|
||||
mvt-android completion
|
||||
```
|
||||
|
||||
The commands print setup instructions by default. To generate a completion script directly, pass the shell name:
|
||||
|
||||
```bash
|
||||
mvt-ios completion bash
|
||||
mvt-android completion zsh
|
||||
```
|
||||
|
||||
MVT only writes completion files or shell configuration when `--install` is passed. See the [command completion documentation](https://docs.mvt.re/en/latest/command_completion/) for details.
|
||||
Module-running `check-*` commands can load custom Python modules with
|
||||
`--load-module PATH` or from a folder set in `MVT_CUSTOM_MODULES`. See the
|
||||
[development documentation](https://docs.mvt.re/en/latest/development/) for
|
||||
details.
|
||||
|
||||
Users can also add top-level commands to `mvt-ios` and `mvt-android` from
|
||||
installed Python packages or local files and folders. See the
|
||||
[custom CLI command documentation](https://docs.mvt.re/en/latest/custom_commands/)
|
||||
for the plugin entry points and `--load-command` interface.

### VirusTotal package lookups
|
||||
|
||||
AndroidQF records APK file hashes in `packages.json`. MVT can optionally look up non-system APK hashes on VirusTotal while checking an AndroidQF acquisition:
|
||||
|
||||
```bash
|
||||
MVT_VT_API_KEY=<key> mvt-android check-androidqf --virustotal /path/to/androidqf-output
|
||||
```
|
||||
|
||||
The `--virustotal` option is disabled by default because it sends APK hashes to VirusTotal and requires network access. It uses the `VT_API_KEY` MVT configuration value, which can also be provided through the `MVT_VT_API_KEY` environment variable.
|
||||
|
||||
To avoid exhausting free VirusTotal API quotas, MVT waits 16 seconds between package hash requests by default. Use `--delay` to change the delay, or `--delay 0` to disable throttling:
|
||||
|
||||
```bash
|
||||
mvt-android check-androidqf --virustotal --delay 30 /path/to/androidqf-output
|
||||
```

## Android Intrusion Logs
|
||||
|
||||
On devices where the user has opted into Android's [**Advanced Protection Mode**](https://support.google.com/android/answer/16339980) and turned on the optional Intrusion Logging featrue, Android can create and archive structured *Intrusion Logs* in an encrypted format. These logs record DNS queries, outbound network connections, process starts, ADB activity and other security-relevant events, and are a high-fidelity complement to the rest of an AndroidQF acquisition. The logs are generated on-device and encrypted before being stored in the Google account associated with the device. The encryption key is protected by the user device PIN. The intrusion log data is not accessible to Google.

MVT utilizes the [Click](https://click.palletsprojects.com/en/stable/) library for creating its command line interface.
|
||||
|
||||
Click provides tab completion support for Bash (version 4.4 and up), Zsh, and Fish.
|
||||
|
||||
To enable it, you need to manually register a special function with your shell, which varies depending on the shell you are using.
|
||||
To enable it, you need to register a completion script with your shell, which varies depending on the shell you are using.
|
||||
|
||||
The following describes how to generate the command completion scripts and add them to your shell configuration.
|
||||
The following describes how to generate the command completion scripts and add them to your shell configuration.
|
||||
|
||||
> **Note: You will need to start a new shell for the changes to take effect.**
|
||||
|
||||
### For Bash
|
||||
|
||||
```bash
|
||||
# Generates bash completion scripts
|
||||
echo "$(_MVT_IOS_COMPLETE=bash_source mvt-ios)" > ~/.mvt-ios-complete.bash &&
|
||||
echo "$(_MVT_ANDROID_COMPLETE=bash_source mvt-android)" > ~/.mvt-android-complete.bash
|
||||
# Generate bash completion scripts
|
||||
mvt-ios completion bash > ~/.mvt-ios-complete.bash
|
||||
mvt-android completion bash > ~/.mvt-android-complete.bash
|
||||
```
|
||||
|
||||
Add the following to `~/.bashrc`:
|
||||
```bash
|
||||
# source mvt completion scripts
|
||||
. ~/.mvt-ios-complete.bash && . ~/.mvt-android-complete.bash
|
||||
[ -f ~/.mvt-ios-complete.bash ] && . ~/.mvt-ios-complete.bash
|
||||
[ -f ~/.mvt-android-complete.bash ] && . ~/.mvt-android-complete.bash
|
||||
```
|
||||
|
||||
### For Zsh
|
||||
|
||||
```bash
|
||||
# Generates zsh completion scripts
|
||||
echo "$(_MVT_IOS_COMPLETE=zsh_source mvt-ios)" > ~/.mvt-ios-complete.zsh &&
|
||||
echo "$(_MVT_ANDROID_COMPLETE=zsh_source mvt-android)" > ~/.mvt-android-complete.zsh
|
||||
# Generate zsh completion scripts
|
||||
mvt-ios completion zsh > ~/.mvt-ios-complete.zsh
|
||||
mvt-android completion zsh > ~/.mvt-android-complete.zsh
|
||||
```
|
||||
|
||||
Add the following to `~/.zshrc`:
|
||||
```bash
|
||||
# source mvt completion scripts
|
||||
. ~/.mvt-ios-complete.zsh && . ~/.mvt-android-complete.zsh
|
||||
[ -f ~/.mvt-ios-complete.zsh ] && . ~/.mvt-ios-complete.zsh
|
||||
[ -f ~/.mvt-android-complete.zsh ] && . ~/.mvt-android-complete.zsh
|
||||
```
|
||||
|
||||
### For Fish
|
||||
|
||||
```bash
|
||||
# Generate fish completion scripts
|
||||
mkdir -p ~/.config/fish/completions
|
||||
mvt-ios completion fish > ~/.config/fish/completions/mvt-ios.fish
|
||||
mvt-android completion fish > ~/.config/fish/completions/mvt-android.fish
|
||||
```
|
||||
|
||||
Fish loads completion files from `~/.config/fish/completions` automatically.
|
||||
|
||||
### Automatic Installation
|
||||
|
||||
MVT can write the completion file and update the relevant shell configuration for Bash and Zsh when you pass `--install`:
|
||||
|
||||
```bash
|
||||
mvt-ios completion bash --install
|
||||
mvt-android completion bash --install
|
||||
```
|
||||
|
||||
Replace `bash` with `zsh` or `fish` as needed. For Fish, `--install` writes the completion file into `~/.config/fish/completions`.

||||

# Custom CLI Commands
|
||||
|
||||
MVT can load additional top-level commands into `mvt-ios` and `mvt-android`.
|
||||
Custom commands are different from [custom forensic modules](development.md#custom-modules):
|
||||
commands add new CLI operations, while modules add analysis steps to existing
|
||||
`check-*` commands.
|
||||
|
||||
!!! warning
|
||||
|
||||
Custom commands run as trusted Python code inside the MVT process. Install
|
||||
or load commands only from sources you trust. MVT does not sandbox
|
||||
third-party commands, and the MVT maintainers do not maintain them.
|
||||
|
||||
## Install a Command Package
|
||||
|
||||
Python packages can register a Click command or group for either MVT CLI. A
|
||||
minimal package can expose this command from `my_mvt_plugin.py`:
|
||||
|
||||
```python
|
||||
import click
|
||||
|
||||
|
||||
@click.command()
|
||||
@click.argument("path", type=click.Path(exists=True))
|
||||
def summarize(path):
|
||||
"""Summarize an acquisition."""
|
||||
click.echo(f"Summarizing {path}")
|
||||
```
|
||||
|
||||
Register the object in the package's `pyproject.toml`. The entry-point name is
|
||||
the command users invoke:
|
||||
|
||||
```toml
|

Use only the iOS or Android group if the command is platform-specific. After
|
||||
installing the package in the same environment as MVT, it appears directly in
|
||||
the appropriate CLI:
|
||||
|
||||
```bash
|
||||
mvt-ios summarize ./ios-backup
|
||||
mvt-android summarize ./androidqf-output
|
||||
```
|
||||
|
||||
For a `pipx` installation of MVT, inject the plugin into MVT's environment:
|
||||
|
||||
```bash
|
||||
pipx inject mvt my-mvt-plugin
|
||||
```
|
||||
|
||||
When MVT is installed in an active virtual environment, install the plugin with
|
||||
`pip` in that environment.
|
||||
|
||||
## Load a Command File
|
||||
|
||||
For local commands that are not packaged, create a Python file that exports one
|
||||
Click command or group named `cli`:
|
||||
|
||||
```python
|
||||
import click
|
||||
|
||||
|
||||
@click.command("case-summary")
|
||||
@click.argument("path", type=click.Path(exists=True))
|
||||
def cli(path):
|
||||
"""Summarize a case directory."""
|
||||
click.echo(f"Summarizing {path}")
|
||||
```
|
||||
|
||||
Pass the file before the custom command name:
|
||||
|
||||
```bash
|
||||
mvt-ios --load-command ./case_summary.py case-summary ./ios-backup
|
||||
```
|
||||
|
||||
`--load-command` can be repeated and also accepts a folder. MVT loads
|
||||
non-hidden top-level `*.py` files in sorted order and skips `__init__.py`.
|
||||
Every loaded file must export one `cli` object.
|
||||
|
||||
To load a file or folder on every invocation, set the platform-specific
|
||||
environment variable:
|
||||
|
||||
```bash
|
||||
export MVT_IOS_CUSTOM_COMMANDS=./ios_commands
|
||||
export MVT_ANDROID_CUSTOM_COMMANDS=./android_commands
|
||||
```
|
||||
|
||||
## Naming and Errors
|
||||
|
||||
Built-in MVT commands cannot be replaced. External command names must also be
|
||||
unique; when installed packages or environment paths collide, MVT keeps the
|
||||
first command and logs a warning. A collision from an explicit
|
||||
`--load-command` is a usage error.
|
||||
|
||||
A package entry point or environment command that cannot be imported appears
|
||||
as a marked broken command without preventing other MVT commands from working.
|
||||
Invoke that command to see its package or file source and the underlying error.
|
||||
An invalid command supplied explicitly with `--load-command` fails immediately
|
||||
with a usage error.
|
||||
|
||||
Installed command packages use the entry-point name as the CLI command name.
|
||||
The entry point must resolve to a `click.Command` or `click.Group`.

## Installed module packages
|
||||
|
||||
Python packages can register modules so they load automatically in every
|
||||
module-running `check-*` command, without `--load-module` or
|
||||
`MVT_CUSTOM_MODULES`. Register an entry point in the `mvt.modules` group in
|
||||
the package's `pyproject.toml`:
|
||||
|
||||
```toml
|
||||
[project.entry-points."mvt.modules"]
|
||||
mvt-plugin-amnesty-custom = "mvt_plugin_amnesty_custom:get_modules"
|
||||
```
|
||||
|
||||
The entry point must resolve to an iterable of `MVTModule` subclasses, or to
|
||||
a callable returning one:
|
||||
|
||||
```python
|
||||
from mvt.common.module import MVTModule
|
||||
|
||||
|
||||
class PackagedModule(MVTModule):
|
||||
supported_commands = (("ios", "check-backup"),)
|
||||
|
||||
def run(self):
|
||||
self.results = [{"message": "packaged module ran"}]
|
||||
|
||||
|
||||
def get_modules() -> list[type[MVTModule]]:
|
||||
return [PackagedModule]
|
||||
```
|
||||
|
||||
Installed modules follow the same rules as other custom modules: each module
|
||||
must declare `supported_commands`, and dependencies are resolved with the
|
||||
standard ordering logic. A broken entry point is skipped with a warning and
|
||||
does not prevent MVT from running. As with custom commands, installed module
|
||||
packages run as trusted code inside the MVT process, so install only packages
|
||||
from sources you trust.
|
||||
|
||||
For a `pipx` installation of MVT, inject the package into MVT's environment:
|
||||
|
||||
```bash
|
||||
pipx inject mvt mvt-plugin-amnesty-custom
|
||||
```
|
||||
|
||||
### Naming module packages
|
||||
|
||||
Name module packages `mvt-plugin-<name>` (import package `mvt_plugin_<name>`),
|
||||
and include the name of the publishing organization or author so packages from
|
||||
different groups do not collide: for example, Amnesty International's custom
|
||||
modules would be distributed as `mvt-plugin-amnesty-custom` with the import
|
||||
package `mvt_plugin_amnesty_custom`.
|
||||
|
||||
The prefix makes module packages easy to find on PyPI and keeps their import
|
||||
names from clashing with unrelated Python packages. It is a convention, not a
|
||||
technical requirement: modules load through the `mvt.modules` entry point
|
||||
regardless of what the package is called, and existing packages with other
|
||||
names keep working. Note that the prefix is also not a mark of authenticity —
|
||||
anyone can publish a package with any available name, so vet a module package
|
||||
and its publisher before installing it, whatever it is called.
|
||||
|
||||
### Module logging
|
||||
|
||||
Modules log through `self.log`, and MVT names the logger for where the module
|
||||
came from. MVT's own modules log under their dotted path (for example
|
||||
`mvt.ios.modules.mixed.whatsapp`). Everything external is namespaced under
|
||||
`mvt.ext` to keep it visually distinct from built-in modules and isolated from
|
||||
MVT's internal logger tree:
|
||||
|
||||
- Installed packages log under `mvt.ext.<package>`, with the `mvt_plugin_`
|
||||
prefix stripped: modules in `mvt_plugin_amnesty_custom` log as
|
||||
`mvt.ext.amnesty_custom.*`.
|
||||
- Files loaded with `--load-module` or `MVT_CUSTOM_MODULES` log as
|
||||
`mvt.ext.<file name>`.
|
||||
|
||||
## Auditing loaded modules
|
||||
|
||||
Because installed module packages load automatically, MVT records where every
|
||||
module came from:
|
||||
|
||||
- `--list-modules` groups the available modules by source: MVT itself
|
||||
(with its version), each installed package (with its version and, when
|
||||
installed directly from a repository, the commit), and each file loaded
|
||||
with `--load-module` or `MVT_CUSTOM_MODULES` (with the SHA-256 hash of the
|
||||
file).
|
||||
- When a command runs with an `--output` folder, the `command.log` file
|
||||
records one line per module source with the source's version or hash and
|
||||
the list of modules loaded from it.
|
||||
|
||||

This JSON file is created by mvt-ios' `WhatsApp` module. The module extracts a list of WhatsApp messages from the SQLite database located at *private/var/mobile/Containers/Shared/AppGroup/\*/ChatStorage.sqlite*, along with one record per chat session (marked with `"record_type": "chat_session"`) containing the first and last interaction dates of each conversation. Chat sessions produce `chat_first_message` and `chat_last_message` timeline events, and group chats additionally produce a `group_created` event. A chat session's last-message date can postdate its newest stored message when the most recent messages in the chat were deleted.
|
||||
|

Recent WhatsApp versions key 1:1 chat sessions by an opaque LID identifier rather than the contact's phone number. The module resolves these using the `ZWAPHONENUMBERLIDPAIR` table from the *LID.sqlite* database in the same app group (or from *ChatStorage.sqlite* itself in versions that store it there), populating `partner_resolved_phone_number` on chat session records and using the phone number in timeline events. Each LID-phone number pair is also extracted as a record (`"record_type": "lid_phone_number_pair"`) and produces a `lid_pair_recorded` timeline event marking when WhatsApp learned the association.

# Check an iOS Sysdiagnose
|
||||
|
||||
`mvt-ios check-sysdiagnose` prepares an iOS sysdiagnose archive for analysis by
|
||||
custom MVT modules. MVT does not include built-in sysdiagnose modules. You must
|
||||
load at least one custom module that explicitly supports this command.
|
||||
|
||||
The command accepts either an extracted sysdiagnose directory or the original
|
||||
gzip-compressed tar archive.
|
||||
|
||||
```bash
|
||||
mvt-ios check-sysdiagnose \
|
||||
--load-module ./sysdiagnose_modules.py \
|
||||
--output ./results \
|
||||
./sysdiagnose_2024.01.02_03-04-05+0200.tar.gz
|
||||
```
|
||||
|
||||
Use `--hashes` to include hashes for analyzed files in `info.json`, and
|
||||
`--list-modules` to display the eligible custom modules without running them.
|
||||
|
||||
## Writing a custom module
|
||||
|
||||
Extend `SysdiagnoseExtraction` to access the archive contents consistently for
|
||||
both directory and tar inputs. Each module must declare the command explicitly
|
||||
in `supported_commands`.
|
||||
|
||||
```python
|
||||
from mvt.ios.modules.sysdiagnose import SysdiagnoseExtraction
|
||||
|
||||
|
||||
class ExampleSysdiagnoseModule(SysdiagnoseExtraction):
|
||||
supported_commands = (("ios", "check-sysdiagnose"),)
|
||||
slug = "example_sysdiagnose"

|
||||
def run(self):

paths = self._get_files_by_pattern("*/example.log")
|
||||
if paths:
|
||||
content = self._get_file_content(paths[0]).decode("utf-8", "replace")
|
||||
self.results = [{"content": content}]
|
||||
|
||||
def check_indicators(self):
|
||||
pass
|
||||
|
||||
def serialize(self, result):
|
||||
return None
|
||||
```
|
||||
|
||||
The base class provides `from_sysdiagnose_folder()` and
|
||||
`from_sysdiagnose_tar()` setup hooks, as well as protected file lookup, file
|
||||
reading, and timezone extraction helpers. IPS crash-report metadata is exposed
|
||||
on `ips_files`.
